Grab the Uninstaller here:
run it; it will uninstall ALL flash player versions
Next let make sure you have the correct processes closed.
Open a CMD prompt Run a Command as Administrator from the Windows 7 / Vista Run box
copy/paste the following one by one or make a bat file to do it all in one step How to Write a Batch File (with Examples) - wikiHow
taskkill.exe /im plugin-container.exe /f
taskkill.exe /im firefox.exe /f
taskkill.exe /im iexplore.exe /f
taskkill.exe /im flash* /f
taskkill.exe /im battle* /f
That should close any flash dependent programs ( that I know of )
next in the cmd window do the following:
ATTRIB -H -S -R C:\Windows\System32\Macromed\Flash /s /d
ATTRIB -H -S -R C:\Windows\SysWOW64\Macromed\Flash /s /d
rmdir "C:\Windows\System32\Macromed\Flash" /s /q
rmdir "C:\Users\%username%\AppData\Roaming\Adobe\Flash Player" /s /q
rmdir "C:\Users\%username%\AppData\Roaming\Macromedia\Flash Player" /s /q
IF exist C:\Windows\SysWOW64 rmdir "C:\Windows\SysWOW64\Macromed\Flash" /s /q
( note IF you are on 32 bit you can eliminate anything with sysWOW64 )
Next try installing the files at the bottom of this page one by one.
Hopefully that will get you up and running. ( why Adobe does not provide a bat file like i have and automate it is beyond me to simplify it for end users)
Full functionality has been restored! Thanks.
